Dassault Aviation not in favour of Thales-Alstom rail tie-up - CEO

PARIS, April 13 (Reuters) - The head of Dassault Aviation

, the biggest shareholder in Thales, said he

was not in favour of pursuing a joint venture in railway

operations between the French defence electronics firm and

transport group Alstom.

Analysts have suggested Thales could be a possible partner

for Alstom at a time when rivals Siemens and

Bombardier are eyeing a potential tie-up of their rail

operations, according to sources close to the matter.

Eric Trappier, chief executive of Dassault Aviation, told

Reuters that he was "not at all" in favour of a similar joint

venture between Alstom and Thales, which is specialised in rail

signalling rather than in train parts.

"We're still pursuing the same vision (...), which has been

well defined for the past two or three years and which consists

of consolidating the rail signalling unit within Thales,"

Trappier said on the sidelines of a news conference in Paris.

A spokesman for Thales declined to comment.
